That's OK Dave. It's over.
All that I wanted is to confirm is that the usage of `tr.Td[1])` was right.
Had I had that faith, there wouldn't have been this email, which apparently
I was focusing on `tr.Td[1])` instead of what I should be focusing.
I.e., the answer I was expecting was just merely,

Using a channel read in the http handler will block the ticker for loop

I've set up a GoLang post request handler that uploads a file to Google

Now I'd like to figure out how I can send the upload progress info back to

Why not use an interface?
type TableSaver func (db *DB)
or
type TableSaver func (tx *Tx) // depending on your needs
Allowing you to:
func (t *Table) SaveTable (...) {}
Which in your example if you wanted use a different SaveTable
implementation for OtherTable you could. Otherwise it would ju

Here’s an overview of what I’ve done, but no quality claim is made.
In package main there’s a global:
type DB struct {
*sql.DB
}
var database DB
In func main() I call an initialization function that reads a JSON
configuration file and does sql.Open with dbname, user, password, host,
port,
Thanks, all!!!

It is *not relevant* what language was used to prepare exploit. It
always melts down to the machine code

I’ve used the Selenium Firefox plugin to test web servers written in Go. It’s
great for end to end testing of a web server because it doesn’t know or care
what the server is written in. It’s only concerned with the resulting HTML.
I recorded some web sessions using the plugin and can then play
